[交流] 【求助】Pd/C催化剂制备相关问题 已有7人参与

有没有哪一个虫子做过Pd/C催化剂的阿?我用的是Pd(NO3)2为前驱体,那Pd是以哪一种形式负载在C上的呢?想用甲醛还原可以直接还原嘛?方程式怎么写阿?急...急阿!
请高手指点迷津!

Pd/C is easy to prepare, you can use impregantion or chemical fluid deposition.
After reduction, the nano-Pd is supported on C. Normally, it is btter for you to use methanol to reduce.

Sorry, I am in Germany. Max-Planck-Institut onyl has English and German input, no Chinese input. You can leave oen E-mail to me. After work, I can use my personal computer to send E-mail to you in Chinese.

你的意思是纳米Pd吸附与碳颗粒表面?我还没明白他们之间是什么作用,或者是以什么方式 support,物理吸附还是有其他作用啊?望不吝赐教

Whether Pd was supported on the suafce or internal channel, it depend on the type of C you used. If you use mesoprous or large porous C, Pd will go into the channel. Or it go on the other side. Both the physical and chemcial adsorption existed, just which is much stronger or which is much weaker. It is related to the treament during the process.
